Vocabulary mission
Move between Arabic and meaning without relying on the order of the cards.
Explain · notice · apply
Study each structure in context, compare accurate and inaccurate forms, then apply it in meaningful Arabic.
What does the structure communicate?
Which word or ending changes?
What must match the noun or person?
Can you use it with new vocabulary?
A sound-ending present verb changes its final ḍamma to fatḥa after أَنْ: نُقَلِّلُ → نُقَلِّلَ. It does not “lose a nūn”.
Name the responsible person or group after عَلَى.
لِكَيْ explains the intended purpose. A sound-ending verb takes fatḥa.
يَنْبَغِي أَنْ + subjunctive present
A sound-ending present verb changes its final ḍamma to fatḥa after أَنْ: نُقَلِّلُ → نُقَلِّلَ. It does not “lose a nūn”.
يَجِبُ عَلَى + noun + أَنْ + subjunctive
Name the responsible person or group after عَلَى.
action + لِكَيْ + subjunctive
لِكَيْ explains the intended purpose. A sound-ending verb takes fatḥa.
أَنْ + one of the five verbs → nūn is omitted
Only the five verbs lose their final nūn: يُعِيدُونَ → أَنْ يُعِيدُوا. Ordinary forms such as نُقَلِّلُ do not contain that nūn.
| Structure | How it works | Accurate example |
|---|---|---|
| Advice with يَنْبَغِي أَنْ | يَنْبَغِي أَنْ + subjunctive present | يَنْبَغِي أَنْ نُقَلِّلَ اسْتِخْدَامَ البِلَاسْتِيكِ. |
| Obligation for a person or group | يَجِبُ عَلَى + noun + أَنْ + subjunctive | يَجِبُ عَلَى الحُكُومَةِ أَنْ تَسْتَثْمِرَ فِي الطَّاقَةِ المُتَجَدِّدَةِ. |
| Purpose with لِكَيْ | action + لِكَيْ + subjunctive | نَسْتَخْدِمُ النَّقْلَ العَامَّ لِكَيْ نُقَلِّلَ الانْبِعَاثَاتِ. |
| The five verbs after أَنْ | أَنْ + one of the five verbs → nūn is omitted | يَجِبُ عَلَى النَّاسِ أَنْ يُعِيدُوا التَّدْوِيرَ. |
Use the complete phrase and its context; do not decide from one isolated word.
Agreement, prepositions and verb endings change what a sentence communicates.
Grammar laboratory
Every answer checks a stated rule, change or agreement decision.
Build · transform · justify
The guided builder develops flexible sentence construction. The three independent tasks then test different skills: grammatical transformation, meaning and coherence, and original sentence production.
Combinatorial builder studio
This guided builder accepts 27 accurate combinations. Build 3 different sentences, changing one meaningful chunk each time. Compare the grammar and meaning before moving to the independent tasks.
اِخْتَرْ جُزْءًا مِنْ كُلِّ قَائِمَةٍ.
0/3 different sentences built.
All three frames are followed by أَنْ and a first-person plural subjunctive verb ending in fatḥa.
Apply the subjunctive after أَنْ
Place the present verb after يَجِبُ أَنْ and mark its ending accurately.نُقَلِّلُ النُّفَايَاتِ.
Begin with يَجِبُ أَنْ.نُقَلِّلَ is not one of the five verbs. It takes a visible fatḥa because it is subjunctive after أَنْ.
Distinguish the five verbs
Select the recommendation in which the final nūn is correctly deleted after أَنْ.The subject is السُّكَّانُ and the base verb is يُعِيدُونَ.
يُعِيدُونَ is one of the five verbs. After أَنْ, the final nūn is deleted: أَنْ يُعِيدُوا.
Build two action-and-purpose sentences
Choose an environmental action, a purpose with لِكَيْ and a context. Underline both subjunctive verbs.لِكَيْ introduces purpose and is followed by a subjunctive present verb ending in fatḥa.

يعيدون is one of the five verbs, so its nūn is omitted after أن.
